Wedding attendee injured amid debris (10)

I believe the answer is:

bridesmaid

I'm a little stuck... Click here to teach me more about this clue!

'wedding attendee' is the definition.
I can't tell whether this definition defines the answer.

'injured amid debris' is the wordplay.
'injured' indicates an anagram.
'amid'+'debris'='amiddebris'
'amiddebris' anagrammed gives 'BRIDESMAID'.

Can you help me to learn more?

(Other definitions for bridesmaid that I've seen before include "match participant" , "one's holding up train perhaps" , "Attendant at wedding" .)

I've seen this clue in the Sydney Morning Herald.
